Designation Root-meansquare value Average over 3 phases Sliding window demand Description 3.3 Measured variables Σ Unit Inst Min Max Inst Min Max DMD Min Max Operating hours counter Oper hours (load runtime) ✓ [s] ([h]) 1) The average over 3 phases can only be called via the communication interfaces or the user defined display. 2) Total reactive power (VARtot), comprising the reactive power of the fundamental (VAR1) and the reactive power of the harmonics (VARn). 3) Reactive power of the fundamental (VAR1) due to the displacement of voltage and current 4) Reactive power of the harmonics (VARn) without the fundamental content due to the power system harmonics (integer multiples of the fundamental frequency) 5) Inductive and capacitive. 6) Off-peak or on-peak. The current tariff is shown on the display. 7) The "+" sign stands for "Import". The "-" sign stands for "Export". 8) Optionally calculated for total reactive power (VARtot), reactive power (VARn), or reactive power (VAR1). 9) The unit depends on the settings: User definable unit or "kWh" or "kVARh" for the pulse counter function. See also Measured variables (Page 169) Measured variables depending on the connection type The total set of representable measured variables is restricted by the method of connecting the device. A measured value that cannot be indicated because of the connection method is shown on the display by means of a broken line "----". The table below shows which measured values can be represented depending on the connection type.
